Here are all the resources that are available for GE heat pump without calling GE and hearing them tell you to call service technician: http://waterheatertimer.org/GE-heat-pump-manuals-by-date.htmlhttp://waterheatertimer.org/Review-GE-Heat-Pump-water-heater.htmlThere is no wiring diagram for the bundles of wires coming from chip control board.As general rule, these things are made to last 10 years, and afterwards will not function or be repairable. It's like a window air conditioner, except connected to water pipes, and connected to computer chip and multiple sensors, each susceptible to failure, and then the machine is used 24 hours a day, 365.Designs have changed continually from 2009 to 2010 to 2012 models.It's likely you got a nice piece of junk with depleted anode rod and failed sensors that stopped working and somebody got rid of it because it wasn't repairable.http://waterheatertimer.org/How-to-recycle-water-heater.htmlAdd a comment If you need further help, I’m available over the phone at https://www.6ya.com/expert/gene_9f0ef4df2f9897e7
remove the two covers one high and one low and set the temp higher. This time of year with colder water comming in the house the water heater has to work harder to raise the temp of the incomming water. In the summer the incommong water is much warmer. 40 gal is a small water heater and you will only get about 15 gal of hot water with the ice cold water entering the water heater as you use the hot water. You can get a bigger water heater. even better is to go tankless and a have never ending hot water and save money at the same time.
Problem has to be bad element or bad thermostat.Test elements for short to ground through metal tank wall:http://waterheatertimer.org/How-to-test-water-heater-element.htmlMake sure factory-installed insulation and cover are re-installed over new thermostats so they do not misread tank temperature.If problem does not show with elements, then replace thermostats again.

Water heater can test for power, but is only receiving 120V instead of 240V. Test that upper thermostat is getting 240V across top two screws of thermostat.

2) Dual element tanks are 240Volt. Thermostats turn off 1 leg of 240Volt circuit. If element is shorted to ground through center of element, it might not trip the breaker. In this case, the bad element would continue heating with 120V through ground wire. http://waterheatertimer.org/How-to-test-water-heater-element.html

About the only other thing I can think of would be replace the reset switch. As long as your are sure you have 220-240 volts to elements and thermostats turned up It sounds like you pretty well have it covered. Thank you.
The reset button kicks out because the thermostat detects overheating. Anything over 150 degrees, the reset kicks out.
This is caused by 4 things. 1) Bad upper or lower thermostat. Thermostat sticking in 'on' position and elements overheating water. 2) Factory-installed insulation and cover are removed 3) Bad element shorted to ground at center of element, and element continues heating with 120V through the ground wire. 4) Loose wire near upper thermostat, that is shorting and causing heat. http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html
Remove access door usually on upper side of unit. Will need to unscrew retaining screws. Under cover is a thermostat that you can adjust to your liking. Reattach cover when done.
More than likely it needs to be replaced if you have to constantly reset it. Shut of power and repalce thermostat, it just snaps in place and easy to remove.
You need to replace the thermocouple. It unscrews from the thermostat on one end, and the other one hooks in a bracket. After replacment make sure the thermocouple bulb is in the pilot flame.
